在iPy Notebook中运行unittest示例时发生AttributeError

python

我是iPython的新手,正在尝试帮助另一位开发人员入门,我们都遇到了相同的问题。

我们正在尝试从https://docs.python.org/2/library/unittest.html#basic-
example在iPython中运行python单元测试示例,
该代码在Windows和ubuntu上的命令行上运行得很好,没有任何修改来自iPy笔记本的代码生成以下异常:

AttributeError: 'module' object has no attribute '/home/myuser/'

文件名是: /home/myuser/example_unittest.ipynb

到目前为止,我没有碰运气的iPython文档和谷歌。任何调试技巧,或解决此问题的线索,不胜感激。

(全栈):

unittest.main() 主要用于命令行执行。

为了在ipython笔记本中运行if __name__ == '__main__'单元测试,请删除部分代码,然后在新的单元格中创建测试套件,然后使用来运行它TextTestRunner

suite = unittest.TestLoader().loadTestsFromTestCase(TestSequenceFunctions)
unittest.TextTestRunner().run(suite)
